The MIC-C/T/P FMEC has one pair of LEDs located on the RJ45 LAN connector. The green LED is on
when a link is present, and the amber LED is on when data is being transferred.
16.4 Optical Service Channel Cards
This section describes the optical service channel cards. An optical service channel (OSC) is a
bidirectional channel connecting two adjacent nodes in a DWDM ring. For every DWDM node (except
terminal nodes), two different OSC terminations are present, one for the West side and another for the
East side. The channel transports OSC overhead that is used to manage ONS 15454 DWDM networks.
An OSC signal uses the 1510-nm wavelength and does not affect client traffic. The primary purpose of
this channel is to carry clock synchronization and orderwire channel communications for the DWDM
network. It also provides transparent links between each node in the network. The OSC is an
OC-3/STM-1 formatted signal.
There are two versions of the OSC modules: the OSCM, and the OSC-CSM, which contains the OSC
wavelength combiner and separator component in addition to the OSC module.
